IMPROVEMENT IN CARBURETERS.

l 'Speoication forming part of Letters Patent Nori 70,097, dated November 16, 1875; application filed July 15, 1875. i

llo all 'whom it may concern.:

Be it known thatl, SAMUEL McKIssocK, of Allegheny, in the county ot' Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Garbureters; and I do hereby declare the following to be a full, clear, and exact descriptionof the'invention, such 'as Will enable others skilled in the art to which it pertains to make and use it,

l reference being had to the accompanying drawings, which iorm Which- Y Figure l is an elevation, partly sectional, of my invention. Fig. 2 is 4a detailvvieW, showing, in perspective, a portion ot' coiled-Wire Pipe. "Y

This invention relates "to that class ot carbureters in which Weights are used to set the machinery in motion to supply air; and consists, chieiy, in the devices adopted for that purpose, and for maintaining a constant and adjustable pressure, and in the construction of the carbureting-tank and its parts.

Referring to the accompanying drawings, A represents an elongated tank, containing Water as a luting for the three air-chambers B C D. These are bottomless, B C pumping the air, and D storing and giving it an adjustable pressure. From the interior of chambers B O are airpipes au', opening in the said chambers, passing down through the bottom of tank A, over and up into chamber D, Where their ends are opened and closed alternately by their respective check-valves b b', pivoted on a bearing on top of the main supply-pipe in the chamber D. These pipes a c feed the pumped air from chambers B C into chamber D. When one chamber is pumping the valve in its supplypipe is open by reason `of pressure of air into D, While the other is automatically closed, thus keeping the air from backing out of D into the other chamber. Air is fed to these chambers B C by the inlet-pipes c c,also supplied With the check-valves d d', which Work alternately by means of rods connected with the Walkingbeamcl. These prevent the air from backing out ofthe pumping-chambers after its en trance thereto.l vlirom the chamber D, above the Water-level, an open-ended pipe, e, passes down into the carbureting-tank. From the tops of chambers B C rise rods, to which are pivoted part of this specification, in

attached the pivoteddogs M. The normal positionof these dogs, by reason of Weights W W', is horizontal, From this position they are pushed down to operate the levers ff' andA .pump-chambers B C by the lugs k on the escapement-Wheel E, which is operated by a cord `and YWeight attached to the drum m, which lworks the Wheel E by a pawl and ratchet.`

Connected with a rod rising from chamber D is" athird pivoted lever, f, with an adjustingcounter-balance, W, for the purpose of controlling the pressure oi' air under the chamber D, and thence into the carbureting-chamber G. This latter consists of a vessel having one or more horizontal partitions with an air-inlet pipe above the iirst,'and a gas-outlet pipe beloW the lowest. In each of these partitioned compartments spiral Walls n are placed, leading from the inlet above to the compartment below, and so on through the series. In these passages are laid, in like manner, spirally- Wound Wires o, one or more, or any equivalent in purpose and effect. These connect with the air-inlet, ending in each compartment at its exit into the one below, and there beginning again. Cotton is loosely packed around Vthese Wires and saturated With the hydrocarbon. The intention is to obtain all the diffusive properties possible for the carburetin g material, and at the same time give free passage to the air. These spirally-coiled Wires constitute porous pipes, the air-passages being through the center of the coils from which the air has access to the saturated packing, so as to become carbureted While freely passing along. The middle portion of the lowest compartment is left open and free from partitions,

Wires, and cotton. The superfluous oil collects here, and when it gets too high a oat, p, in connection With the oil-feed pipe, stops the flow until the supply is reduced. The Wound Wire forms a sort of open-sided pipe, to convey the air and give it free access to the carbureting material,'so as to absorb the greatest pos-v sible quantity of the carbon therein. A perforated or slotted pipe would answer the purpose, but I consider the wire the best.

The modus operandi is as follows: The operating-Weight, being wound upon the drum m, sets wheel E in motion. Lugs k operate dogs i 'i' alternately, and they, by means of cranks l1, h', operate the levers ff', which thus work the pumping-chambers B C. Air comes into these through the inlet-pipes c c', and is forced out through pipes a. a into pressure and storing chamber D, prevented from returning by check-valves b b. From this itis forced through pipe e into carbureter Gr, where it winds around through the wires o in a spiral through the cotton or other fibrous substance saturated with the carbureting material, finally reaching the open chamber at the bottom, whence it passes out through the feed-pipe to the burners or gasometer.

' Having fully described my invention, what I claim, and desire to secure by Letters Patformed by the spirally-coiled wires o, exter` nally packed, and having open channels through the center of the coils, with lateral access to the packing, substantially as described.

3. In combination with the chambers B C D, the pipes a a and c c', with their respective valves b b and d d', connected and operating alternately, as shown and described.

4. In combination withthe chambers B C D and their operating-levers f f f, respectively, the adjusting counter-balances W W' W", as and for the purposes set forth.

5. The alternately-actin g pum ping-chambers B G, in combination with the intermediate storing and pressure chamber D, pipes a a', connecting said chambers. valves b b', carbureting-chamber G, and pipe e, substantially as described and shown.

6.l The combination, with the alternatelyacting pumping-chambers B C, weighted levers ff', and ratchet-wheel E, having double row of alternating teeth, of the dogs e' z" and links h h', substantially as described, and for the purpose set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 9th day of July, 1875.
